If your computer monitor isn’t displaying anything when it’s turned on, you’re not alone. This is a common problem that can have a variety of causes. In this article, we’ll discuss some of the most common causes of this issue and how to fix them. Stay tuned, because we’re about to show you how to get your monitor working again!
Checking the external Cable
One of the most common causes of this problem is a loose or disconnected cable. If you’re using a desktop computer, check to make sure that all of the cables are properly connected to both the computer and the monitor. If you’re using a laptop, make sure that the connection between the computer and the monitor is secure. You may also want to try connecting the monitor to a different port on your computer.
Checking the Graphics Card
Another common cause of this problem is an issue with the computer’s graphics card. If you’re using a desktop computer, you can access the graphics card by opening up the case and removing the cover from the expansion slot that houses the card. Once you have access to the card, remove it from the slot and inspect it for any visible damage. If you don’t see any damage, try re-seating the card in the slot and replacing the cover. If you’re using a laptop, you’ll need to take it to a qualified technician to have the graphics card inspected and repaired.
Checking the Peripheral Hardware
Check all the peripheral hardware attached to your computer including the keyboard, mouse, and monitor. Make sure that they are securely plugged in and that none of the cords or cables are loose. If everything appears to be plugged in correctly, unplug each device one by one and then plug it back in again. This will help to reset the connection and might fix the problem.
Checking the CMOS Battery
Check the CMOS battery. This battery provides power to the system clock and memory, so if it’s not working properly, it could cause problems with your display.
To check the CMOS battery, simply remove it from the motherboard and test it with a multimeter. If the battery is dead, replace it with a new one.
Checking the RAM stick
Checking the RAM stick is one of the very first things which needs to be done in this case. Sometimes, a loose contact between the RAM and its slot can also cause this problem. In that case, just remove the RAM gently from its place and put it back again making sure that it is inserted properly. If you are still facing the same issue, then try to remove the RAM completely and put it in another slot or in another computer. This will help you determine if the problem lies with the RAM or not. If the display works fine on another computer, then it means that there was some problem with the RAM which is now solved. But if you are still facing the same issue, then the problem lies elsewhere.
Checking the Monitor
The very first thing which you should do when you face this problem is to check the monitor. Many times, it happens that the user gets so panic that they immediately start thinking about some big hardware issue inside the CPU. But that’s not always the case. Sometimes, the problem lies with the monitor only. There are a couple of things which you should check in the monitor. First of all, check if the power cord of the monitor is properly plugged into the socket or not. Many times, it happens that we accidentally unplug the power cord while working around the CPU and we forget to plug it back in. This can be a very simple reason behind this problem. Another thing which you should check is the ON/OFF button of the monitor. Many times, it happens that we accidentally hit the OFF button while working around and forget to turn it back ON. So, these are a couple of things which you should check in the monitor first before moving on to other hardware parts.
These are some of the most common reasons for this problem. If you have followed all the steps and the problem still persists, then there might be a more serious issue with your computer. In this case, it is best to take it to a professional for further diagnosis.
